2 Sausages Specification Part 1: Red meat Sausages 0 FOREWORD Sausage is a meat product obtained by stuffing meat and associated ingredients into casing. Sausage may be raw, cooked and /or smoked. It was found necessary to prepare this Tanzania standard due to an increased production and importation of Sausages in Tanzania. This Tanzania standard has been prepared to ensure safety and quality of Sausages traded in the country. In the preparation of this Tanzania, standard considerable assistance was drawn from KS 59-1:2017 Sausage Specification Part 1: Raw, cooked red meat sausages and sausage meat published by the Kenya Bureau of Standards. In reporting, the results of a test or analysis made in accordance with this standard, if the final value observed or calculated, is to be rounded off, it shall be done in accordance with TZS 4 (see clause 2). 1.0 SCOPE This Tanzania standard specifies requirements, methods of sampling and test for red meat sausages from cattle, sheep, goats, pigs and other animals intended for human consumption. 2.0 REFERENCES For the purpose of this Tanzania standard, the following references shall apply.
